Log in to your Referral Factory account, you will need to be on at least the Basic plan of Referral Factory to gain access to an API token.
Navigate to the Settings section and look for the 'Webhooks and API' tab, scroll down to the “API” section, and generate your API access token.
Please note that only one active access token is allowed per account. Generating a new token will automatically deactivate any existing tokens for that account.
